Google buys streaming radio service Songza

The streaming music business is heating up.

Google(GOOGL, Tech30) announced Tuesday that it's acquiring streaming radio service Songza, which creates free playlists tailored for various activities and times of day. The companies declined to reveal the purchase price.

Songza, launched in 2010, will complement Google Play Music All Access, the subscription streaming service Google unveiled last year. Google said Songza will continue to function independently for the time being while it "explore[s] ways to bring what you love about Songza to Google Play Music."

"We'll also look for opportunities to bring their great work to the music experience on YouTube and other Google products," Google added.
